DISCUSSION. 
The CHAarRMAN: We are all greatly indebted to Mr. Webber for his 
admirable lecture, and also to the Government of the United States for 
having sent him to tell us what they are doing. His lecture has been a 
practical illustration of the remarks I made at the beginning, of science 
and practice working harmoniously together for the mutual benefit of 
each. 
Mr. C. C. Hurst: I should like to ask Mr. Webber, in the case of 
those hybrids which he said resemble one parent or the other, to be kind 
enough to tell us whether they resemble one parent in all characteristics, 
or simply in one or two. 
Mr. Wesser: In all, so far as can be observed. In growth, 
character of the stem, and so on, they resemble one or the other parent. 
Mr. Batrson: I should like to know whether Oranges, when grown 
from seed fertilised with pollen of the same variety, produce good fruit. 
As I understand it, they are not propagated generally by seed. . 
Mr. Wesser: So far as the Orange is concerned, Oranges always 
produce Oranges. Seedlings of the Orange give Oranges ; and seedlings 
of the Pomolo give Pomolo. Crossings of different species seem to be 
very rare. 
The CHarruan: You spoke just now about a nucleus fertilising the 
germ cell, and thereby giving one hybrid plant out of three seedlings, 
the other two of which represented the female. I should like to know 
whether you have ever had two representing the male and one the female 
out of the three. 
Mr. Wepser: In answering that question it is necessary to bear in 
mind that in these cases we have differences. In some instances we 
note supernumerary embryos developing. In the case of Oranges I think 
they are developed from the cells. In the case of double fecundation the 
nucleus unites with the two pollen nuclei, which finally produces an 
endosperm; but secondary embryos are not developed from that endo- 
sperm, and, as | understand it, we cannot expect any case of double 
fecundation.
